Solar2D General Questions/Discussion

My app was rejected because the total size for all the system files is too big (over 20MB of images used for offline use).

How do I set the “do not backup” attribute in Corona? or is there a work around? Thanks Bosco

From Apple:

How do I prevent files from being backed up to iCloud and iTunes?
